Abstract

A microcontroller for use in battery charging and monitoring applications is disclosed. The microcontroller includes a microprocessor and various front-end analog circuitry such as a slope A/D converter and a multiplexer for allowing a plurality of analog input signals to be converted to corresponding digital counts indicative of signal level. The microcontroller also includes an I2C interface for supporting a bi-directional two wire bus and data transmission protocol that is useful for serially communicating with other peripheral or microcontroller devices. By making use of the I2C interface, the microcontroller can be programmed while in the end application circuit. Such a feature allows customers to manufacture boards with unprogrammed devices and then program the microcontroller just before shipping the product. This allows the most recent firmware or a custom firmware to be programmed.
